dlp vs. rear lcd projection. What's the diff?

641 Views 8 Replies 6 Participants Last post by  TechnoCat
I think the subject line says it all. I have a Sony kdf-50we655, and I love it. I noticed while looking around the forum that it seems that it is not a dlp television, but instead is rear lcd projection.

Can anybody illuminate me on the differences?

No kidding? Like I didn't try that first...The only results are completely off topic. Maybe you should have done the search before dropping the s bomb on me.

Any positive contributions to this thread?
Thanks doc. Don't know why that didn't show up in my search.
I was in the market recently and hadn't payed too much attention to the different technologies before that. As soon as I went out to the stores to look at the TVs I saw the rainbow effect (RBE) on DLPs. I immediately scratched those off the list. With the burn-in problem of plasmas and the large heavy sizes os CRTs, I felt LCD projection was my only choice.

The TV's are both Micro display devices, the biggest difference is how they create the image on your TV. LCD RP use liquid crystal and DLP uses a mirrored MMD. Both TV's can deliver great PQ, but they both also have flaws just like everything else. Hope that helped..

You are MR Obvious all of the sudden????????????
I'm not an expert, owning neither yet but having shopped for both for well over a year. (Even got a letter publishing in S+V on it!) But...

LCD RP appeared to me to be worse at low-light scenes. For example (my specific example), the series Babylon 5 has dark blue and grey uniforms, in outer space, and the battleships (e.g. white star) are dimly lit. On an LCD RP, at a certain point everything just vanishes. You have ghost arms and hands and then a bit of a body, with a ghost head.

Also fast moving high-contrast images (think laser beams or a slapping hand) left trails briefly.

DLP didn't have that problem, and seemed more vivid also, but on some CGI scenes had an amazing amount of what I could only call "shimmer". No non-DLPs had this. It's possible this was equivalent to RBE, but showed particularly hard on this source - the scene is a rotating space ship, so your eye focus is constantly moving with the little blocks rather than staying on a given pixel.

Those are the big differences I noticed. Contrast (or better darks at any rate) favored DLP, lack of shimmer on CGI favored LCD, so I bought neither. But the differences between DLPs, for example, is bigger than the difference between LCD and DLP RPs. For SD on a high-res fixed-pixel unit, for example, I think scaling probably matters a lot more than the technology used to get the display up there, among contemporary technologies.

But again, I'm the least expert of anyone here. I just happened to be comparing those two specific technologies myself because I dread plasma burn-in.
